Four governors and two ministers were in the state to welcome the governor to the party.
The Ebonyi State Governor, David Umahi, has officially joined the ruling All Progressive Congress (APC) from the Peoples Democratic Party (PDP).
On the day of his defection, however, another aide of the governor resigned from his government.
At the event in Abakaliki, the state capital, the National Caretaker Chairperson of the All Progressives Congress (APC) and Governor of Yobe State, Mala Buni, handed over the APC flag, broom, and the party card to Mr Umahi as a symbol of his joining the party.
Governor Buni said that the official admission of Governor Umahi into the party marks a new beginning in the history of Ebonyi State.
He stated that President Muhammadu Buhari, since assumption of office, has been fair to everyone irrespective of political affiliation.
According to him, when over 27 states could not pay salaries, the president gave out bailout funds to all the states without putting into consideration party affiliation.
He stated that apart from the bailout funds and the Anchor Borrowers scheme, which many states have benefitted from, Ebonyi State and the South-east in general, would be fully integrated into the national programme and policies of the present administration.
He commended the Ebonyi State Governor, David Umahi, for being courageous and taking a bold step that would liberate the South-east region despite attacks and criticism from some quarters.
He called on other South East governors to follow the footsteps of Governor Umahi by joining the APC.
